Rule 6. Avoid Cheap Filters

Bargain-priced paper coffee filters yield inferior coffee, according to the experts. Look for “oxygen-bleached” or “dioxin-free” paper filters (e.g., Filtropa, Melitta). Alternatively, you may wish to invest in a long-lived gold-plated filter (e.g., SwissGold). These are reputed to deliver maximum flavor, but may let sediment through if the coffee is ground too finely.
